CHARLOTTE — The Carolina Panthers have waived kicker Justin Medlock and replaced him with Graham Gano.

The Panthers (2-8) signed Gano, a free agent, to a two-year deal after Medlock missed his last three field goals.

Gano spent 2009-11 with the Washington Redskins, playing in 36 games and converting 59 of 80 field goal attempts (73.8 percent) with a long of 59 yards.

Gano entered the NFL as an undrafted rookie free agent with Baltimore in 2009 before being released by the Ravens.

Medlock started the season 7 of 7 before having a kick blocked against Washington. He then missed field goals against Denver and Tampa Bay. Medlock’s second-quarter miss from 40 yards on Sunday against the Bucs would have put the Panthers up 17-10.

Carolina lost to Tampa Bay 27-21 in overtime. The Panthers face the Eagles (3-7) on Monday night.

Dolphins get tight end

Tight end Kyle Miller has been awarded off waivers to the Miami Dolphins, and they waived receiver Jabar Gaffney.

Gaffney joined the Dolphins in early October. He had the best season of his career last year with Washington, then signed with the New England Patriots and was released at the end of training camp.

Seattle rookie suspended

Seattle Seahawks rookie safety Winston Guy has been suspended for four games without pay for violating the NFL’s policy on performance-enhancing substances.

Guy’s agent, Greg Linton, says the positive test was the result of an ingredient found in an over-the-counter supplement that his client took. He says Guy has no intentions of appealing his suspension and called it an innocent mistake.

Reed avoids suspension

Baltimore Ravens safety Ed Reed avoided a one-game suspension for late hits after an appeal.

He instead will be fined $50,000.

Reed was suspended for one game without pay on Monday by NFL vice president of football operations Merton Hanks for his third violation in three seasons of the rule prohibiting helmet-to-helmet hits against defenseless players.

The third violation occurred in Sunday night’s game at Pittsburgh: Reed’s hit to the head of receiver Emmanuel Sanders.

Reed appealed the ruling in a phone session with NFL hearing officer Ted Cottrell. The NFL Players Association represented Reed, who also participated.
