The Washington Capitals have recalled forward Paul Carey and defenseman Connor Carrick from their American Hockey League affiliate while also re-assigning center Zach Sill and defenseman Aaron Ness, the team announced.

The return of Sill and Ness is most likely related to both nearing waiver eligibility, as after 10 games played or 30 days on the NHL roster since last clearing waivers, a player again needs waivers to be sent down to the AHL. Sill has played in nine games, Ness eight.

Ness was an emergency recall on Thursday morning, as the team was unsure if Taylor Chorney would be able to play because of flu symptoms. Players on emergency recall must be returned to the AHL when the player he is replacing returns, so since Chorney played against the Islanders, Ness’s recall ended.

The Capitals have six healthy defensemen, and Brooks Orpik is still on long-term injured reserve. Carrick will most likely be the extra defenseman as the team plays four of its next five games on the road. The 21-year-old has appeared in three games with the Capitals this season, and he has registered six points (one goal and five assists) in 37 career NHL games with Washington, most of which were during the 2013-14 season. He recently represented the Hershey Bears at the AHL All-Star Classic.

Carey could contend for a fourth-line forward role, as third-line center Marcus Johansson isn’t expected to return until the team’s three-game road swing next week, at the earliest. The 27-year-old has played in two games with the Capitals this season and has earned one assist in 24 career NHL games with Washington and Colorado. He signed with Washington as a free agent on July 8, and he has registered 31 points (13 goals and 18 assists) in 43 games with the Hershey Bears this season.
