ORCHARD PARK, N.Y. (AP) – Drew Bledsoe’s face was red and his vision fuzzy on Thursday while insisting he intends to play this weekend despite experiencing aftereffects of a mild concussion.

“Ah, you know, a little dizzy,” the Buffalo Bills quarterback said, when asked whether he was still having headaches. “But I think I’m going to be all right.”

Bledsoe did not participate in Thursday’s practice, a day after he left in the middle of practice complaining of nausea, headaches and vision problems.

The Bills added Bledsoe to their injury report, listing him as probable for Sunday’s game against the Giants at the Meadowlands. Bills coach Gregg Williams initially attributed Bledsoe’s problem to an upset stomach, calling it “a bug going around.”

Citing a neurological exam that came back normal, Bledsoe said he plans to practice on Friday, which will help him determine whether he can play.

The Bills have only one other quarterback, veteran Alex Van Pelt, on their active roster. If Bledsoe’s troubles persist, the team would likely have to activate Randy Fasani, who played with Carolina last season, off of its practice squad.

Bledsoe recalled when the injury occurred, at the end of 5-yard run when he was kneed in the back of the helmet in the third quarter of a 17-14 loss to Indianapolis last Sunday. He didn’t miss a play but followed up by missing three straight passes and getting sacked once before throwing a 13-yard completion to Bobby Shaw.

“I knew, immediately, I was going to have some problems with it,” said Bledsoe of the hit. “I had a headache Monday and a headache Tuesday, but was feeling OK. But then, when I got out here and started moving around, that’s when I started to notice a little more dizziness.”

Bledsoe hasn’t had a history of concussion problems over his 11-year NFL career, saying the only other time he had one was in 2001. That’s when he also sustained a severe chest injury that all but ended his final season in New England, following a legal tackle by New York Jets linebacker Mo Lewis.

Bledsoe’s loss would be another blow to a Bills offense that’s already banged up and sputtering.

Eric Moulds, their leading receiver, has been limited, missing three of the last six games with a partially torn groin. Leading rusher Travis Henry has continued playing despite a hairline fracture just above his right ankle.

Then there’s Buffalo’s offensive line, of which all five starters are nursing injuries.

The Bills have also had trouble scoring. Bledsoe’s 1-yard plunge last Sunday ended a three-game stretch without a touchdown.

Buffalo travels to face the Giants having gone four straight road games without scoring an offensive touchdown, going back to a 38-17 win at Jacksonville on Sept. 14.

“Our focus right now really is on us and our execution,” Bledsoe said. “We’re making way more mistakes than we should make at this point in the season.”

And they’re manifesting themselves particularly on third down. On third down we’re making too many mistakes. That’s really where our focus is.”

Moulds expressed concern about Bledsoe’s health.

“I’m concerned a little bit,” Moulds said. “I know Drew’s a pretty smart guy. He knows his body better than anybody. … And the decision he makes as far as playing or not playing, I’m pretty sure it’s a difficult one for him because he wants to be out there all the time.”

Earlier this week, Bills cornerback Antoine Winfield created a stir when he referred to the offense as being “predictable” and sticking to a pass-first philosophy despite lacking in deep-threat receivers.

Bledsoe said he had not read Winfield’s comments.

“I don’t know what Antoine said. I just know that he’s a tremendous teammate and a tremendous player,” Bledsoe said. “And anything that he said was obviously in the best interest of the team.”
