Out for over seven weeks with a concussion, Gutierrez is expected to play five innings in the field for Tacoma. Depending on how he feels, the plan is for him to take a day off or be in the lineup as the designated hitter on Sunday.
Gutierrez has had several setbacks since first suffering the concussion on June 28, but a recent change in medications has apparently helped curb recurring headaches.
The prolonged effects from the concussion, plus a bout with plantar fasciitis, have limited the former Gold Glover to just 13 games this season.
"I'm not going to put a timeline on it," Mariners manager Eric Wedge said. "We're just going to take it day-by-day and see how he goes."
