Answer based on context:

For many years, the Rose Bowl had the largest football stadium capacity in the United States, eventually being surpassed by Michigan Stadium (107,601). The Rose Bowls maximum stated seating capacity was 104,091 from 1972 to 1997. Some of the seats closest to the field were never used during this time for UCLA regular season games, and were covered by tarps. Official capacity was lowered following the 1998 Rose Bowl. Slightly different figures are given for the current capacity, for the lower level seats behind the team benches are not used for some events since the spectators can not see through the standing players or others on the field. UCLA reports the capacity at 91,136. The Tournament of Roses reports the capacity at 92,542. The 2006 Rose Bowl game, which was also the BCS championship game, had a crowd of 93,986. In the 2011 contest between TCU and Wisconsin, the listed attendance is 94,118.  As of 2008, the Rose Bowl is the 11th List of American football stadiums by capacity, and is still the largest stadium that hosts post-season bowl games. For concerts held there, the Rose Bowl holds almost 60,000 people. The stadiums 2014 remodeling removed the lower "lettered row" seats on each side behind the players benches and provide access in and out of the stadium for the lower sections of the Rose Bowl, restoring its original design.

How many seats were reduced in the Rose Bowl using the UCLA reports?
12955
