The reported trade between the Miami Dolphins and Philadelphia Eagles that would send linebacker Kiko Alonso and cornerback Byron Maxwell to Miami, is either being held up or is completely off over injury concerns, according to reports.

The deal was pending physicals, with Alonso's past knee injury being cited as a concern. According to reports, however, it's Maxwell's shoulder that has held it up.

Now it's just a matter of figuring out whether the Dolphins have completely scuttled the trade, as some have reported, or whether the two sides are still trying to make it work.

Compensation for the Eagles hadn't been established, though the Dolphins do own the eighth pick in this year's draft. FOX Sports NFL Insider Mike Garafolo had reported that the Eagles will have to pick up a portion of Maxwell's salary.

Maxwell played four seasons with the Seattle Seahawks, the last as a starter, before joining the Eagles as a free agent. He started 14 games for Philadelphia and intercepted two passes.

Alonso, who is 25 years old, joined the Eagles as part of the blockbuster trade that sent LeSean McCoy to the Buffalo Bills. He missed 2014 with a knee injury and played in just 11 games with the Eagles in 2015.
