The Marlins activated Weathers (lat) from the 60-day injured list Thursday to start Thursday against the Nationals.
Weathers will make his return to the Marlins' rotation for his first big-league start since June 7. The left-hander has been limited to only five starts in the majors this season, first missing time due to a forearm strain and more recently a lat strain. Weathers threw 68 pitches in his second of two rehab outings, so his workload will be relatively limited versus the Nats.
