SOUTH BEND, Ind.(AP) -- Notre Dame's high-flying offense got one
of its most potent players back with the return of receiver
Michael Floyd.

The 6-foot-3, 220-pound sophomore was second in the nation in
receiving yards at 160 yards a game when he broke his left
collarbone trying to make a catch against Michigan State on
Sept. 19 in the third game of the season.

Floyd, who had a plate placed on the bone the next day, was
"hooting and hollering going down the steps" after receiving the
news Monday night that he was cleared to play, coach Charlie
Weis said Tuesday.

Doctors, including noted orthopedic surgeon Dr. James Andrews of
Alabama, said Floyd's collarbone had healed enough to play - and
then Floyd's mother gave the OK.

"He came back to me and said, 'I'm ready to go,"' Weis said.

Floyd said although Weis doesn't plan to play him every play, he
feels ready for as much as the Irish coaches want to give him.

"I feel like I'm ready to go. I feel good," the soft-spoken
Floyd said.

Weis said he isn't worried about Floyd playing tentatively
because of the injury when the 19th-ranked Fighting Irish (6-2)
play Navy (6-3) at Notre Dame Stadium on Saturday.

"The biggest thing he's going to have to happen is to get
tackled once," Weis said. "He'll get hit in practice some, but I
doubt we're going to try him out in practice. I think we're
going to have to wait and find that out as it happens in game."

Floyd, who injured his knee last season against Navy, won't be
wearing anything special to protect his shoulder, Weis said.

Floyd went full speed at practice Tuesday afternoon, leading the
Irish receivers through the drills. There was no heavy hitting,
but he did run through five teammates as they hit receivers with
pads. Floyd was the only receiver not wearing long sleeves in
the 40 degree weather.

Floyd said he took a few hits and landed on the shoulder several
times in practice Tuesday and it felt fine. When asked if he
felt as good as he did before being injured against Michigan
State, Floyd said he felt better because he had stitches in his
knee in that game.

"I'm ready to go," he said. "I can do everything."

The Irish also received some bad news. Backup quarterback Dayne
Crist is gone for the season after tearing his anterior cruciate
ligament in his right knee against Washington State over the
weekend. Crist is scheduled to undergo surgery Friday. He is
expected to be out four to six months.

Evan Sharpley, a senior who cut his minor-league baseball season
short to come back for a fifth season, will be Jimmy Clausen's
backup.

Sharpley was the No. 2 quarterback the past three seasons,
starting two games in place of the injured Clausen in 2007.

Receiver John Goodman, who played quarterback as a senior at
Bishop Dwenger High School in Fort Wayne, will practice some at
quarterback this week and is now the third-string QB, Weis said.

"He really won't be getting any reps there because Sharpley
needs to get all the reps we can give him to have him ready to
go," Weis said.

The bigger concern for the Irish might be next spring - so long
as Clausen, who has been hobbled by turf toe on his right foot
since the Michigan State game, remains healthy. Clausen is
second in the nation with a pass efficiency rating of 164.25 and
there is speculation he could turn pro after his junior season,
although he has said he hasn't thought about that yet.

Weis has said he and Clausen have agreed to wait until the first
week of December to talk about the NFL. But if he does turn pro
and Crist takes six months to recover, the Irish wouldn't have a
quarterback on scholarship unless a recruit enrolls in January.

The team also said defensive end Kapron Lewis-Moore is probable
against Navy, right guard Trevor Robinson is doubtful and
tailback Armando Allen Jr. is day to day. All three have
sprained ankles. Reserve tight end Bobby Burger (neck) remains
out.
