Keyser (upper body) was placed on non-roster injured reserve by the Sharks on Monday, Curtis Pashelka of The San Jose Mercury News reports.
The Sharks announced in mid-September that Keyser was facing a long-term absence due to an upper-body injury, so his placement on non-roster injured reserve isn't particularly surprising. Once he's cleared to return, the 27-year-old will likely report to AHL San Jose.
