Resigning Sekera avoided an arbitration hearing scheduled for July 25th. He was tendered an offer two weeks ago.
He is coming off arguably his best NHL season, although his post-season effort was limited to two games due to an upper body injury he sustained before the post-season. The 25-year-old defenseman posted 29 points (3 goals, 26 assists) and was plus-11 in 76 regular season games.
Sekera will earn $11 million over four years ($4,750,000 signing bonus by July 2012).
Ellis, 29, spent 14 games with the Buffalo Sabres in the 2010-2011 season. The left winger was pointless in these games, and was minus-4.
Ellis registered ten goals and 31 points in more than 50 games he played with the Sabres's AHL affiliate (until this season), the Portland Pirates.
After the purchase of the Rochester Americans on May 17, 2011 by Sabres owner Terrance Pegula and clearing various obstacles, it was announced on June 24, 2011 that the Rochester Americans would become the new AHL-affiliate of the Sabres.
