BEREA — Browns’ coach Eric Mangini said Friday morning that rookie guard Shawn Lauvao won’t practice for the second straight day with an injured ankle. Mangini didn’t rule him out for Sunday’s opener in Tampa Bay.

The starting right side of the offensive line remains undecided, according to Mangini. Floyd Womack, who returned to practice this week after arthroscopic knee surgery, joins John St. Clair and Tony Pashos in the mix to start at guard and tackle. Womack and St. Clair can play guard and tackle, while Pashos is more of a pure tackle.

“There are some good combinations we could use in there,” Mangini said.

Other notes from Mangini’s news conference:

** Safety and special teamer Nick Sorensen will practice for the first time Friday since suffering a concussion on a helmet-to-helmet hit Aug. 28 against the Lions. He hasn’t been ruled out for Sunday.

** Rookie cornerback Joe Haden will rotate in with the base defense against the Buccaneers — replacing either Eric Wright or Sheldon Brown — and will start in the nickel package against three wide receivers. Haden covers an outside receiver, while Wright slides inside to the slot.

** Mangini said offensive coordinator Brian Daboll is much more confident in his second year on the job.
