Brissett (hamstring) was limited in Wednesday's practice, Marcel Louis-Jacques of ESPN.com reports.
Brissett was able to check back into Sunday's loss to the Buccaneers after injuring his hamstring earlier in the contest, but he still seems to be dealing with lingering soreness. Tua Tagovailoa (ribs) resumed practicing Tuesday and is eligible to come off injured reserve this weekend against the Jaguars in London, but the Dolphins haven't yet brought him back to the active roster. For the time being, Miami's quarterback situation is uncertain, but Brissett would revet to the No. 2 role if Tagovailoa is cleared to play Week 6.
