Below is the updated news:

In the first three quarters of the Raiders' season opener against the New England Patriots, star tight end Brock Bowers made a significant impact, notching five receptions for 103 yards and securing four first-downs. However, a knee injury in the fourth quarter has thrown a spanner in the works.

Bowers exited the game after a play on the drive, clutching his knee before receiving treatment on the sidelines. Despite being listed as 'questionable' to return, he played no further part in the game.

Initial reports suggest that the injury may not be overly serious, with Bowers himself giving an optimistic update. He promised a quick return to the field, indicating that the extent of the injury is not severe and he could recover rapidly. However, no detailed information about the exact type or expected recovery time was provided.

The Raiders' athletic training staff prevented Bowers from returning to the game, a decision that was met with disappointment from the young tight end. Pete Carroll, the Raiders' head coach, stated that Bowers will have more tests to determine his injury status.

Carroll also mentioned that the next three days are crucial for Bowers' recovery. With the Raiders hosting the Los Angeles Chargers in their home opener on Monday Night Football in Week 2, Bowers will have an extra day of rest to help him recover.

Michael Mayer stepped into the lineup when Bowers was out and had four receptions for 38 yards. The Raiders clinched a 20-13 road victory over the Patriots at Gillette Stadium, a win that was marred by Bowers' injury.

Pete Carroll made history on Sunday night by becoming the oldest head coach in NFL history, just eight days before he turns 74. Despite the concern over Bowers' injury, Carroll remains optimistic about the Raiders' prospects for the season.

Ian Rapoport, a renowned NFL insider, reported that Bowers was limited with a knee injury during the game. He also noted that Bowers was walking around fine post-game, which is a good sign. Rapoport mentioned that Bowers will have more tests to determine his injury status.

As the Raiders await further news on Bowers' injury, they will be hoping that he can recover quickly and return to his impressive form. With the talent and potential that Bowers possesses, the Raiders will be eager to have him back on the field as soon as possible.
