TAMPA, Fla. -- New starting quarterback Mike Glennon hasn’t been able to practice with his two starting wide receivers Wednesday and Thursday.

Vincent Jackson (ribs) and Mike Williams (hamstring) each missed their second straight day of practice. That’s less than an ideal situation, but Williams said he and Jackson already have chemistry with Glennon, who is replacing Josh Freeman.

“Everybody keeps worrying about that, but we’ve been working with him the whole year," Williams said. “There’s never been a practice where it’s just all Josh. It’s been Josh and Mike and Josh and Mike, and then just Josh on Sundays. Now, it’s going to be Mike on Sunday."

Williams estimated he had as many practice reps with Glennon as he did with Freeman during training camp and the preseason.

Williams also was very optimistic about his hamstring.

“I’m playing Sunday, 100 percent," Williams said.
