Martin, TN (My Sportsbook) - Tennessee-Martin men's basketball coach Bret Campbell has announced his resignation and the school has promoted assistant Jason James to the vacant position.

Campbell said his decision had to do with something that occurred during the operation of the summer basketball camps on campus.

"Questions arose regarding decisions I made concerning the operation of the summer basketball camps on campus," Campbell said in a statement released by the university. "I understand the concerns over mistakes that were made. These issues are strictly related to the summer camps and have nothing to do with the NCAA or any of our current or former players."

The school's release did not elaborate on the circumstances.

"I deeply regret Bret's resignation, but I want to assure our stakeholders that the decisions he made regarding summer camps were completely unrelated to his responsibilities under NCAA rules as they related to recruiting, student welfare, academics or any other area of under his supervision," said UT-Martin athletic director Phil Dane.

Campbell spent the past 10 years at UT-Martin and last season led the Skyhawks to their first Ohio Valley Conference regular season title with a berth in the NIT. The team finished a school-best 22-10, giving him a record of 125-167 during his tenure.

"The men's basketball program is clearly in a better position today than when I first arrived 10 years ago," Campbell added. "That is why the time has come for me to turn the program over to my assistant coach and friend, Jason James. I am confident Jason will maintain the enthusiasm currently in place and continue what we have started."

James spent the past seven years as an assistant under Campbell, last year acquiring the added title of assistant head coach.
