Item 1.   Security and Issuer.
	  --------------------

               This Amendment No. 3 (the "Amendment") hereby
amends and supplements the Statement on Schedule 13D originally
filed with the Securities and Exchange Commission on May 15,
2000, as amended (the "Schedule 13D") by CBS Broadcasting Inc.
("CBSBI"), Westinghouse CBS Holding Company, Inc. ("W/CBS HCI"),
Viacom Inc. ("Viacom"), NAIRI, Inc. ("NAIRI"), National
Amusements, Inc. ("NAI") and Mr. Sumner M. Redstone with respect
to the Common Stock, par value $.01 per share (the "Common
Shares"), of SportsLine.com, Inc., a Delaware corporation
("SportsLine" or the "Issuer") with its principal executive
office located at 2200 West Cypress Creek Road, Fort Lauderdale,
Florida 33309.

Item 4.   Purpose of the Transaction
	  --------------------------

          Item 4 is amended and restated in its entirety as
follows:

          The Issuer's Common Shares were acquired by the
Reporting Persons, other than CBSBI and W/CBS HCI which
previously owned the subject shares, pursuant to the merger of
CBS Corporation, of which CBSBI and W/CBS HCI were, respectively,
indirect and direct wholly owned subsidiaries, with and into
Viacom on May 4, 2000.

          On March 5, 2003, CBSBI and the Issuer entered into a
letter agreement (the "Letter Agreement"), pursuant to which:

     (i)  the Agreement dated as of March 5, 1997, between the Issuer
          and CBSBI, as amended (the "Agreement"), was amended to provide
          that, in lieu of the Issuer's obligations to issue to CBSBI
          Common Shares having a fair market value of $20,000,000 on each
          of April 1, 2003 and July 1, 2004, the Issuer will:

          (A)  issue to CBSBI on April 1, 2003, the lesser of (1)
               such number of Common Shares having a $20,000,000
               fair market value on April 1, 2003, and (2) such
               number of Common Shares as would result in CBSBI
               and its affiliates' aggregate beneficial ownership
               interest in Issuer's Common Shares not exceeding
               39.9% and defer the remainder of the $20,000,000
               owing to CBSBI until July 1, 2004, and

          (B)  issue or pay to CBSBI on July 1, 2004:

               (1)  (a) such number of Common Shares having a
                    $20,000,000 fair market value on July 1, 2004
		    plus such number of Common Shares having a
                    fair market value on July 1, 2004 equal to the
                    fair market value of the Common Shares deferred
                    from April 2003 (as described in (A) above)
                    (such aggregate value owing by SportsLine to
                    CBSBI on July 1, 2004 being the "July 2004 Value")
                    or, if that number exceeds 49.9%, (b) such
                    number of Common Shares as would result in
                    CBSBI and its affiliates' aggregate beneficial
                    ownership interest in Issuer's Common Shares
                    not exceeding 49.9%,

               (2)  in cash the lesser of (a) the remaining
                    amount of the July 2004 Value, if any, owing
                    by the Issuer to CBSBI and (b) $5,000,000,
                    and





                                              Page 9 of 10 Pages


               (3)  the remaining amount of the July 2004
                    Value, if any, owing to CBSBI, at the
                    Issuer's election, in cash or Common Shares,
                    based on the fair market value on July 1,
                    2004 (if the Issuer elects Common Shares,
                    CBSBI may elect to defer the receipt of such
                    Common Shares until October 1, 2005, and on
                    October 1, 2005 CBSBI will receive Common
                    Shares equal to the value of the deferred
                    Common Shares based on the fair market value
                    on October 1, 2005); and


     (ii)     CBSBI withdrew its request made by letter dated
         December 23, 2002, to register 11,422,312 Common Shares
         on a Form S-3 shelf-registration statement pursuant to
         Section 3.4 of the CBS/SportsLine Stockholder Agreement
         dated March 5, 1997 between the Issuer and CBSBI, as
         amended.

          Any description of the Letter Agreement is qualified in
its entirety by reference to the Letter Agreement attached as
Exhibit 1 to this Amendment.

     The Reporting Persons have no current plan or proposal that
relates to, or would result in, any of the actions enumerated in
subparagraphs (a) through (j) of Item 4 of Schedule 13D.
Notwithstanding the foregoing, the Reporting Persons may, at any
time and from time to time, purchase additional Common Shares of
the Issuer and may dispose of any and all Common Shares of the
Issuer held by them.


Item 6.   Contracts, Arrangements, Understandings or Relationships with
          Respect to Securities of the Issuer.
	  -----------------------------------

          Item 6 is amended as follows:

          "Except as described in Item 4 above, none of the
Reporting Persons have entered into, or amended any existing
agreement with respect to the Common Shares or other securities
of the Issuer since the prior statement on Schedule 13D, or
amendments thereto, filed by certain of the Reporting Persons and
any predecessor thereof.

          "The information set forth under Item 4 above is
incorporated by reference."
