Michael Coffie had difficulty landing clean punches on Joey Abell before Abell suffered a right biceps injury during the second round Saturday night in Los Angeles.

Abell appeared to hurt his right arm while throwing a punch at Coffie, who was backed against the ropes. With Abell bent over, Coffie caught him with a left to the body and right uppercut to the head as Abell was falling to the canvas.

Abell reached his feet, but he couldn’t continue. Referee Rudy Barragan stopped their scheduled eight-round bout 49 seconds into the second round.

Coffie’s win was televised by FS2 from Microsoft Theater.

The 34-year-old Coffie, a U.S. Marine from Brooklyn, upped his record to 11-0 and recorded his eighth knockout. The 39-year-old Abell (35-11, 33 KOs, 2 NC), of Coon Rapids, Minnesota, lost by knockout or technical for the ninth time in a lengthy career that began in August 2005.

Abell landed on his side with 2:25 to go in the second round once he sustained that arm injury and Coffie caught him with those two punches. Coffie expressed surprise when Abell went down, but he later realized what happened.

Abell landed a right hook with about 1:15 to go in the opening round. Coffie couldn’t connect with clean shots during the opening round, when Abell mostly moved out of his punching range.
