Middleton was reassigned to AHL San Jose on Monday.

EDGE Analysis

Middleton has been held without a point in his four NHL appearances this season. With Mario Ferraro (upper body) expected back for Friday's contest, Middleton would've likely been watching from the press box. The23-year-old blueliner could be recalled as an insurance body after the holiday break, though.

The Sharks promoted Middleton from AHL San Jose on Thursday.

EDGE Analysis

Middleton owns minimal fantasy value at the NHL level, having collected just one point through five career games. He tallied 19 points over 57 games with AHL San Jose last year but hasn't seen the same offensive success in the early going this year, collecting just a pair of assists through 13 contests.

The Sharks assigned Middleton to AHL San Jose on Wednesday.

EDGE Analysis

Middleton was called up Tuesday and played against the Coyotes, logging 8:51 of ice time, a blocked shot and a hit. The Sharks don't play again until Saturday versus the Blues, and Middleton could be recalled again if Mario Ferraro (upper body) isn't ready to go.

Middleton's recall coincided with Antti Suomela (undisclosed) being activated from injured reserve. Joachim Blichfeld was sent down to make room for Middleton on the active roster. Middleton will likely serve as defensive depth while with the Sharks.

The Sharks assigned Middleton (upper body) to AHL San Jose on Tuesday.

EDGE Analysis

Middleton has been sidelined since suffering an upper-body injury after logging just 2:13 of ice time in San Jose's season opener. The 23-year-old blueliner will spend the majority of the campaign in the minors, so he won't be a viable fantasy option in 2019-20.

Middleton is dealing with an upper-body issue and isn't expected to be ready to return from injured reserve until at least mid-November, Curtis Pashelka of The San Jose Mercury News reports.

EDGE Analysis

One of three San Jose blueliners on IR, Middleton looks to be further behind in his recovery process than Dalton Prout (upper body) and Radim Simek (knee), who were both seen skating after Tuesday's practice. Considering that Middleton had only entered the San Jose lineup Oct. 4 against the Golden Knights since Prout got hurt two days earlier, the former may be a regular in the press box by the time he's healthy again.

Coach Peter DeBoer said Sunday that Middleton (undisclosed) has a four-to-six week timetable for a return, Curtis Pashelka of The San Jose Mercury News reports.

EDGE Analysis

Middleton left last Friday's game against the Golden Knights with the injury, and landed on IR a day after. This news proves that the defenseman is dealing with a serious injury, even though the specifics haven't been announced. As long as Middleton is sidelined, look for Trevor Carrick or Tim Heed (upper body) to draw into the lineup.

Middleton (undisclosed) was placed on injured reserve Saturday.

EDGE Analysis

Middleton left Friday's game versus the Golden Knights in the first period and did not return. The decision to place him on IR means Middleton will miss San Jose's next three games, at the minimum. In a related move, the Sharks promoted Trevor Carrick from AHL San Jose.
