Aggie updates

Head coach DeWayne Walker said the Aggies could have as many as four or five new players on its roster by the time fall practices roll around in early August.

Walker said the team will look to address its secondary — both at cornerback and at safety — as well as wide receiver, linebacker and possibly at running back.

“There's a good chance we'll add some guys,” Walker said.

Some injury updates:

Quarterback Matt Christian injured his left collarbone — its his non-throwing shoulder — and has not been playing as often in recent practices. He did play briefly in last weekend's scrimmage. He should be 100 percent for the start of the season.

Also, Seth Smith said he will play on Saturday during the team's spring game. Smith injured his left shoulder during last weekend's scrimmage, but said it felt fine and he was ready to play. It's his left shoulder — not the same shoulder he separated last year during the second half of the season.
