Gross-Matos (knee) was a limited participant in Thursday's practice, Adam Caplan of SiriusXM NFL Radio reports.
Gross-Matos missed San Francisco's Week 1 win over the Jets, and he opened this week as a DNP on Wednesday. He was at least able to practice in some capacity Thursday, and his participation in Friday's session will provide a better sense on whether he will play in Week 2 against the Vikings.
