49ers QB Brock Purdy Returns to Practice After Elbow Surgery

Purdy completed some passes in his first practice back from elbow surgery.
He admitted to some rust but showed off his arm strength on some throws.
Purdy will gradually increase his workload as he continues to recover.
He suffered the elbow injury during the NFC Championship game in January.
The 49ers are optimistic about Purdy's progress with over a month until the regular season.
