After a strong NHL debut, the Sharks center Macklin Celebrini will have to wait a week for his second appearance. The team announced today (Twitter link), that he was placed on injured reserve; defender Jack Thompson was recalled from AHL San Jose to take his place on the roster.

Celebrini was the first pick in the draft in June and after taking some time to think about his plans for this season, he decided to forego the remainder of his college eligibility and turn pro. He didn’t see much action in just two of six games in pre-season, but that didn’t stop him from making a strong debut, picking up two points.

One of the reasons he didn’t see much action during the exhibition season was because he struggled with a nagging lower body issue during training camp. Now he’s dealing with a lower-body injury again, which may be related to what he’s been through the last few weeks. Since it’s still so early in the season, it makes sense to give Celebrini some rest now and try to completely eliminate the problem of him not playing at full health.

As for Thompson, the 22-year-old is in the final year of his entry-level contract and his first full year with the Sharks after being acquired from Tampa Bay at the trade deadline. Last season, he participated in three NHL games between the two teams and collected 41 points in 62 AHL games.

While it may seem strange that a defenseman was brought in to replace a forward, San Jose only had six healthy blueliners on its active roster Shakir Mukhamadullin And Marc Edouard Vlasic both injured. Thompson will now give them some security on the back end while the Sharks still have 14 available forwards on their roster.
