Irish QB Dayne Crist shaken up

SOUTH BEND, Ind. -- Notre Dame quarterback Dayne Crist left the field early in the first quarter of Saturday's game against Michigan at Notre Dame Stadium after he was injured scoring on a 1-yard quarterback sneak on the Fighting Irish's opening drive.

Crist, who played well in last week's 23-12 victory over Purdue, his first game as Notre Dame's starting quarterback, was having problems seeing out of his right eye after diving into the end zone with 11:19 left to play in the first quarter.

Crist returned to the field for Notre Dame's opening possession of the second half. After throwing incomplete on his first attempt, Crist fired a 53-yard touchdown to freshman T.J. Jones, which cut Michigan's lead to 21-14 with 12:42 left to play.

Crist was replaced by freshman Tommy Rees, who threw an interception on his first pass attempt. After Michigan's Denard Robinson threw a 31-yard touchdown to Roy Roundtree on the next play to tie the score at 7-7, Rees was replaced by Nate Montana for the rest of the first half. Montana also threw an interception and then overthrew the end zone on the final play of the half after the Irish had reached the Michigan 3.

Montana is the son of legendary former Notre Dame and San Francisco 49ers quarterback Joe Montana. The Fighting Irish failed to pick up a first down in their first three possessions after Crist was hurt.

Notre Dame was also with special teams coordinator and defensive line coach Mike Elston. Elston was unable to coach in Saturday's game against Michigan because of illness.

A school spokesman said Elston was not at the game.

Elston, who played linebacker at Michigan, was on first-year Notre Dame coach Brian Kelly's staff at Cincinnati last season.
