"We're excited to have both Brandon and Josh here representing Auburn later this month in the Senior Bowl," said Steve Hale, president of the Senior Bowl. "They have both had great careers and are considered to be top prospects at their respective positions."
Mosley, who transferred to Auburn from Coffeyville Community College in Kansas prior to his junior season, earned second team All-SEC honors as a senior. He had an outstanding junior season, too, as a starter on Auburn's undefeated, national championship team.
"First of all I feel blessed to be in the situation and really honored and thankful for the Senior Bowl asking me to come," the six-foot-six, 305-pound lineman said. "It's a huge privilege and I certainly appreciate it and it's a dream to be able to play in the Senior Bowl and continue on to the next level.
Brandon Mosley played tight end and defensive end in junior college prior to coming to Auburn, where he converted to offensive tackle.
"I want to show that I can be the tackle that they need in the NFL and show that I've got what it takes, and really just want to work hard to prove that to them and hopefully I'll be able to do that," added Mosley, who is originally from Jefferson, Ga., High where he was a football and basketball standout.
A former walk-on from Carrollton, Ga., High, Harris delivered the snap on the game winning field goal for last season's Auburn victory over Oregon in the national championship game.
Placed on scholarship prior to his junior year, Harris won praise from Auburn special teams coach Jay Boulware for his hard work and consistency as a field goal and punt snapper.

"It's just really a blessing," Harris said of his invitation to play in the Senior Bowl. "My time at Auburn was incredible. As a walk-on I just never thought I'd end up in this position to now be able to try to fulfill a childhood dream of mine and play in the NFL and this will be a great opportunity to get that exposure.
"It's good to know that I'll get to wear a helmet with that AU logo on the side one last time," Harris added. "Auburn just means so much to me and it always will and now that my playing days are over we get to go out there and represent the Auburn family one more time."
Harris, who was a three-sport athlete in high school, is the grandson of Jimmy Morrow, who played on the 1957 Auburn national championship team. He turned down offers to play at other colleges to walk-on at Auburn.
The Senior Bowl annually attracts more than 800 NFL scouts, coaches and player personnel staffers to the event in Mobile. The game will be televised by the NFL Network.
