The Chiefs on Tuesday released wide receiver Steve Breaston and tight end Kevin Boss.

Both players figured in their plans as recently as the start of last season, but neither was a productive player, for different reasons, in 2012. Boss, who joined the Chiefs as one of their big free-agent additions last year, caught just three passes for 65 yards and a touchdown before his season ended in the second game of the season in Buffalo because of a concussion.

The Chiefs will save almost $7 million in cash with the moves. Breaston was due $4 million in salary and bonuses, Boss was due $2.75 million.

Boss had a history of concussions before he joined the Chiefs, so they may have had some concerns about his ability to play again. The Chiefs didn’t wait long after his injury in Buffalo before they declared him out for the season.

Breaston was one of the Chiefs’ main free-agent additions in 2011 and he was their second-leading receiver that year, catching 61 passes for two touchdowns. But last season he lost his starting spot to Jon Baldwin and fell from favor with the coaching staff.

Breaston, though healthy, was often inactive as the Chiefs used other players at wide receiver. He caught just seven passes for 74 yards.
