Nine undrafted rookies and no tackle

The Carolina Panthers added nine undrafted free agents to their roster on Monday and none were offensive tackles.

So between the six players selected in the draft and the nine undrafted pickups, the Panthers didn't get one player at the left tackle position that was considered a primary need.

That, as general manager Dave Gettleman said on Saturday, is an indicator of how comfortable the Panthers are with the players on the roster -- primarily Byron Bell and Nate Chandler -- competing to replace retired left tackle Jordan Gross.

The 15 newcomers, along with several qualifying players from the roster and 25 to 35 tryout players will participate in a rookie mini-camp on Friday and Saturday.

Here's a look at the undrafted players added to the roster:

Denicos Allen, LB, Michigan State

Had 19.5 career sacks and 46 tackles for loss. A fast, athletic player who is undersized at 5-11, 218. Remember Sam Mills, whose statue is in front of the stadium, was 5-9 and 229 pounds. He wasn't drafted, either.

Philly Brown, WR, Ohio State

Had 63 catches for 771 yards and 10 touchdowns this past season. Returned 41 punts for the Buckeyes the past two seasons.

Carrington Byndom, CB, Texas

Lean at 5-11 and 177 pounds, but fast with a 4.35 40 times at Texas pro day. Tied for team lead with 15 passes broken up.

Adarius Glanton, LB, Florida Atlantic

Every class needs a small-school prospect, and this 6-1, 215-pounder who ranked third in tackles at FAU is that.

Marcus Lucas, WR, Missouri

At 6-4, 218 Lucas is a lean, tall receiver who needs to spend time in the weight room. He had 46 catches for 509 yards and three touchdowns this past season.

Andrew Norwell, G, Ohio State

An imposing figure at 6-6 and 315 pounds. Ranked 22 out of 165 guards at the combine in skills drills.

Darrin Reaves, RB, Alabama-Birmingham

A versatile back who rushed for 1,971 yards and 25 touchdowns the past two seasons. Also caught 70 passes for 596 yards and three touchdowns.

Shaq Rowell, DT, West Virginia

Good size at 6-3, 311, but production wasn't great this past season with no sacks and no game with more than seven tackles.

Jared Wheeler, C, Miami (Fla.)

Versatility is his strength. He made six starts as a senior, two at center, one at left guard and three at right guard.
