The Miami Dolphins are considering backing out of a trade agreed to earlier this week with the Eagles because of their concern about a shoulder injury suffered by cornerback Byron Maxwell, league sources told ESPN's Ed Werder and Chris Mortensen.
The Dolphins were to acquire Maxwell and linebacker Kiko Alonso from the Eagles for draft-pick compensation, but the trade was contingent upon Maxwell and Alonso passing physicals and could not be official before the league's new year opened at 4 p.m. ET Wednesday.
As of Tuesday night, sources said the Dolphins considered the trade dead because of their medical staff's concern over Maxwell's injury, which forced him to finish the 2015 season on injured reserve.If they go through with the trade, the Dolphins would be inheriting a huge contract for Maxwell, who signed a six-year, $63 million deal with the Eagles as a free agent last season.
The Eagles had cleared Maxwell on his physical and were more concerned with Alonso passing his physical because of his history of knee injuries. Each team has its own standards for physical exams.
A source said the Eagles and Dolphins had agreed to exchange places in the first round of the upcoming draft as part of the trade. The Eagles would have moved from the 13th pick in the first round to No. 8.
Maxwell was the Eagles' big free-agent signing last season but struggled in his role as No. 1 cornerback. He was inconsistent in coverage and recorded just two interceptions and 64 tackles. He suffered what the Eagles described as a sprained shoulder in Week 15 against the Arizona Cardinals and did not play again.
Alonso battled through injuries and had a career-low 43 tackles and one interception in 11 games last season. He is a former second-round pick of the Buffalo Bills.
Both players were additions made by former Eagles coach Chip Kelly, who was fired late in the 2015 season.
