Pittsburgh signed Fitzpatrick off its practice squad to the 53-man roster Thursday, Teresa Varley of the Steelers' official site reports.
With Diontae Johnson (hamstring) listed as doubtful for Week 2, Fitzpatrick will be available to potentially provide reinforcement at wide receiver Monday night against the Browns. If he can find his way onto the field, Fitzpatrick will be a secondary option on a passing offense that looked anemic, to put it lightly, in Week 1.
