At long last, the Philadelphia Union have announced some action this offseason, declining options on five players.

Those not returning are midfielders Corben Bone and Fred, and forwards Conor Casey, Brian Brown and Cristhian Hernandez, while the Union also announced that Brian Carroll is out of contract.

Bone, who spent four largely indifferent seasons with Chicago, was drafted by the Union in Stage One of the 2013 Re-Entry Draft. He made just two MLS appearances totaling 13 minutes, capped by a red card after just one minute May 14 against Kansas City. The 26-year-old spent the end of the season on loan with USL Pro side Wilmington Hammerheads.

The 35-year-old Fred was signed via a Waiver Draft in late March after training with the club through most of the preseason. Fred appeared in 11 matches in his second stint with the Union, scoring the game-winning goal against New York July 16.

Hernandez was signed as a Homegrown Player before the 2012 season. He played in two matches, totaling 26 minutes in 2012, then spent most of the last two seasons with Harrisburg City. This year with the Islanders, he was limited to just 15 minutes while floating around several positions.

Brown spent the last four months of the regular season on loan from Jamaican club Harbour View FC. He played in eight games (one start) and scored twice, notching the game-winning goal against Kansas City Aug. 1, then scoring against SKC in a 2-1 win Oct. 18.

Casey, acquired via Stage Two of the 2012 Re-Entry Draft, scoring 18 goals and seven assists in 56 matches with the Union. Casey scored six of his eight MLS goals this season in a six-match stretch from May 31-July 16.

The Union’s roster stands at 24 players ahead of this week’s Expansion Draft (Wednesday) and the two phases of the Re-Entry Draft (Friday, then next Thursday).

Declining options doesn’t close the door to returns for any of the players, though it would be on renegotiated deals. Casey made $192,000 last year. Carroll raked in $185k, while Fred made $65k and Hernandez made $74k.
