The Jaguars are signing Gray off the Dolphins' practice squad, ESPN's Adam Schefter reports.
With T.J. Yeldon (knee) unable to finish Sunday's win over the Colts, the Jaguars were left with Denard Robinson and Joe Banyard in the backfield. The early-week transaction is a bad sign for Yeldon's chances of suiting up for Sunday's game against the Falcons, but it is also possible that the Jaguars are just being cautious. Robinson will get most of the work if Yeldon misses time, with Gray and Banyard perhaps chipping in.
