Ledin is known for his physical style of play and formed during the 2005–06 Elitserien season, together with linemate Emil Kåberg, a duo called The Bruise Brothers.

The Bruise Brothers responded by posing for a photo after winning the final, covered in gold paint, presenting the cup and Ledin kissing Kåberg's chin.

After four seasons with HV71, Ledin sought a mutual release from the club, and returned to hometown team, Luleå HF, on a two-year contract on May 23, 2013.

Ledin made his international debut in 2005 before finally appearing in his first IIHF tournament in a fourth-placed finish at the 2007 World Championships in Moscow, Russia.
