Tackle Bradley Sowell blocking with the first-team offensive line at training camp on Monday.

Bradley Sowell may not be the most talented player on the Cardinals' offensive line, but there's something to be said for a dependable veteran backup.

That could be the case with Sowell, as he practice

d with the first unit at right tackle for the second straight day on Tuesday. While first-round pick D.J. Humphries also mans the position, Sowell is looking like the player coach Bruce Arians will turn to if starter Bobby Massie is unavailable for a stretch of the regular season.

Sowell started at left tackle for 12 games in 2013 after the Cardinals traded Levi Brown and contributed on special teams last year. He's never been penciled in as a key part of the core over the past three years, but has still proven to be a valuable piece.

"I know what's expected of me," Sowell said. "It's kind of the next-man-up thing around here. I'm going to do my best to pitch in on a really good team that's depending on me."

Sowell has played left tackle in college and in the NFL, but said moving to the right side isn't an issue.

"I've always had to work both sides and know what to do," Sowell said. "Now that I know I'm going to be all right for a while, I can really work on honing in."

Sowell wasn't the only backup to get work with the starting offensive line on Tuesday. Guard Mike Iupati left practice early with an apparent injury, and Ted Larsen filled in. Iupati's status likely won't be updated until Arians talks to the media on Wednesday morning.

IMPROVED HEALTH THROUGHOUT THE ROSTER

The

injury list is one of the shortest it's been since the beginning of training camp. All of the running backs participated in practice on Tuesday, and inside linebacker Darryl Sharpton (hip) and defensive end Josh Mauro (back) returned.

Those still out are cornerback Darren Woodard (groin), linebacker Shaq Riddick (hamstring), linebacker Sean Weatherspoon (hamstring), cornerback Jonte Green (hamstring), wide receiver Michael Floyd (hand) and tackle Rob Crisp (knee).

"It's nice to have everybody pretty healthy, especially going into this ballgame," Arians said. "Hopefully we can keep them that way."

Floyd, who the team hopes to get back for the start of the regular season, sent a Tweet on Tuesday which said the stitches from his hand were removed and he's progressing toward recovery. He dislocated three fingers while trying to catch a pass on Aug. 5. He spent time before practice running the stairs at University of Phoenix Stadium and then 100-yard sprints on the field trying to keep up with his conditioning.

FOOT INJURY SHELVES WAGENMANN

Linebacker Zack Wagenmann was waived-injured after breaking his foot for a second time in the past few months. The undrafted free agent out of Montana originally broke it in a pre-draft workout.

"We loved him on tape coming out," Arians said. "It's just an unfortunate thing when you get those foot injuries."

The Cardinals added safety Anthony Walters to take Wagenmann's place on the 90-man roster.
