CHARLOTTE, N.C. (AP) -- The Carolina Panthers are hopingByron Bell gives them the stability and dependability at right tackle that Jeff Otah never could.
Coach Ron Rivera said Tuesday that he views Bell, a second-year player out of New Mexico, as the team's starting right tackle this season. Bell earned a roster spot last year as an undrafted rookie and started 12 games after Otah landed on injured reserve for the third straight season.
Bell will be counted on to help protect quarterback Cam Newton, the AP Offensive Rookie of the Year in 2011.
''He played pretty doggone well last year,'' Rivera said of Bell. ''We were one of the top scoring teams in the league last year with him in there at right tackle. We think a year of experience bodes well for him and he'll continue to grow.''
However, Bell can still stand to improve.
He was flagged for 14 penalties last season, fourth-most in the league, and allowed five sacks as a rookie, according to STATS Inc.
Rivera said Bruce Campbell, acquired in a trade earlier this offseason with the Oakland Raiders, and Garry Williams, who is coming off a season-ending knee injury, will also compete behind Bell at right tackle. Rivera said the depth at that position made it easier to pull the trigger on the Otah trade.
''We have three good young offensive tackles that can help contribute and be a part of what we want to do and a veteran on the other side (at left tackle) with Jordan Gross,'' Rivera said.
The decision to trade Otah on Monday came at almost exactly the same time the Panthers acquired wide receiver Louis Murphy from the Oakland Raiders in exchange for a late-round pick in 2013. Essentially, the draft picks involved in both trades cancel themselves out, meaning the Panthers got Murphy in exchange for Otah.
Like Otah, Murphy has battled injury problems.
He missed five games last season with a groin injury. Rivera said Murphy tweaked his hamstring last week and may be limited at the start of training camp.
Murphy is expected to compete for the No. 3 receiver spot along with David Gettis, who is coming off a torn ACL last summer, and Kealoha Pilares.
Although Gettis has been placed on the physically unable to perform list, the move was mostly procedural. The Panthers can remove Gettis from that list as soon as he's deemed ready to practice.
Rivera has previously said Carolina's starting receivers will be Steve Smith and Brandon LaFell.
The Panthers also got good news at Tuesday's minicamp session for selected veterans and rookies when three of their defensive stalwarts - linebackers Jon Beason and Thomas Davis and defensive end Charles Johnson - were back on the field together for the first time together since last year's season opener.
