Kieran Foran is in doubt to face his future National Rugby League teammates when the Warriors host Canterbury on Friday.
Coach Stephen Kearney says five-eighth Foran is recovering from a quadriceps injury suffered in the Warriors' 34-12 win over Gold Coast a week- and-a-half ago.
A bye week had given the Kiwis international extra time to recuperate and a late call will be made on his availability.
"We'll give him until as late as possible, probably until the captain's run on Thursday," Kearney said.
"But he's progressing and we're hopeful he'll be OK."
Foran ended months of speculation about his future in April by signing a three- year deal with the Bulldogs.
Meanwhile, Kearney confirmed the Warriors won't seek a replacement this season for departing assistant coach Steve McNamara.
Former England coach McNamara was granted an early release after being appointed head coach of Super League club the Catalans Dragons.
Kearney believes remaining assistants Andrew McFadden and Stacey Jones are sufficient to see out the campaign.
Club great Jones will be the lone attack coach, having previously shared the role with McNamara.
