ANN ARBOR, Mich. (AP) The Big House is getting a bit smaller - at least in terms of capacity.

Michigan Stadium will officially hold only 107,601 after seating adjustments announced Friday. That's down from 109,901 but still leaves the 88-year-old venue as college football's largest.

The school says the most noticeable changes are related to improving accessibility under the Americans with Disabilities Act. Seats had to be eliminated to widen aisles and install hand railings.

Football attendance peaked at Michigan Stadium with a crowd of 115,109 for a win over Notre Dame in 2013, which set a record for a college or NFL game. There were more empty seats last year as the team struggled, but ticket sales are up again after the hiring of new coach Jim Harbaugh.
