Item 1.              Security and Issuer.

                     This Statement constitutes Amendment No. 3 ("Amendment No.
3") to the statement on Schedule 13D (the "Original 13D") filed with the
Securities and Exchange Commission by Leucadia National Corporation
("Leucadia"), and its subsidiaries, LUK Acquisition I, LLC ("LUK I") and LUK
Acquisition II, LLC ("LUK II"), with respect to the common stock, $0.01 par
value per share (the "WilTel Common Stock"), of WilTel Communications Group,
Inc., a Nevada corporation ("WilTel").

                     Unless otherwise indicated, all capitalized terms used
herein have the meanings ascribed to them in the Original 13D.


Item 4.              Purpose of Transaction.

                     On July 29, 2003, Leucadia withdrew its May 15, 2003
request that the Board of Directors of WilTel (the "Board") take action under
the Stockholders Agreement to allow Leucadia to make an exchange offer of 0.3565
of a Leucadia common share for each share of WilTel. Leucadia's request was for
the Board to permit an offer to go forward now for the 52.6% of WilTel not
already owned by Leucadia rather than having to wait until October 15, 2004, at
which time the proposed exchange offer would be permitted to be made under the
Stockholders Agreement. A copy of Leucadia's press release is attached hereto as
Exhibit 2 and is incorporated herein by reference.

                     Subject to and depending upon availability at prices deemed
favorable by Leucadia, Leucadia, directly or through its subsidiaries, may
purchase additional shares of WilTel Common Stock from time to time in the open
market, in privately negotiated transactions with third parties or otherwise,
subject to compliance with the terms of the Stockholders Agreement and the
transfer restrictions contained in WilTel's Articles of Incorporation.

                     Except as set forth above, the Beneficial Owners have no
present plans or intentions which would result in or relate to any of the
transactions described in subparagraphs (a) through (j) of Item 4 of Schedule
13D.


Item 7.              Material to be Filed as Exhibits.

                     1. Agreement among the Beneficial Owners with respect to
the filing of this Amendment No. 3.

                     2. Press release of Leucadia National Corporation dated
July 29, 2003.

and belief, I certify that the information set forth in this statement is true,
complete and correct.
