O'Reilly entered the NHL's COVID-19 protocols Tuesday and will miss at least 10 days of action, Jim Thomas of The St. Louis Post-Dispatch reports.

EDGE Analysis

O'Reilly will be sidelined until Nov. 7 against Anaheim at a minimum. This is obviously a big loss for the Blues and fantasy managers alike, as O'Reilly has gotten off to a hot start this year, having racked up two goals and five points through the first five games of the season. With O'Reilly facing an extended absence, Robert Thomas will likely be tasked with taking on a larger role for the foreseeable future.

O'Reilly logged an assist and two shots on goal in Monday's 3-0 win over the Kings.

EDGE Analysis

O'Reilly set up David Perron for an empty-net goal in the third period. With two goals and three assists during a season-opening five-game point streak, O'Reilly is off to a strong start. The center has added 10 shots on net and a plus-3 rating while winning 16 or more faceoffs in four of the Blues' five contests. He's a set-and-forget option in fantasy at this early stage of the season.

O'Reilly scored a power-play goal on two shots and won 17 of 25 faceoffs in Saturday's 7-3 win over the Kings.

EDGE Analysis

O'Reilly has two goals and two assists during his season-opening four-game point streak. The star center has added eight shots on net and a plus-2 rating while contributing a faceoff win percentage at 60 or better in all four contests. The 30-year-old is looking well worth the fifth- or sixth-round pick fantasy managers needed to use to draft him.

O'Reilly notched an assist, fired two shots on goal and won 16 of 24 faceoffs in Wednesday's 3-1 win over the Golden Knights.

EDGE Analysis

The center has gotten on the scoresheet in all three of the Blues' games this year. O'Reilly helped out on Brandon Saad's second-period tally. With a goal, two assists, six shots on net and a plus-1 rating so far, O'Reilly is providing solid value for fantasy managers who likely drafted him in the middle rounds.

O'Reilly recorded an assist and two shots on goal in Monday's 7-4 win over the Coyotes.

EDGE Analysis

O'Reilly didn't have to play a starring role Monday in a game where 13 of the Blues' 18 skaters recorded a point. He assisted on Jordan Kyrou's second tally in the second period. With two points, four shots and a plus-1 rating through two contests, O'Reilly has started the season fairly well. He'll continue to log big minutes in a top-line role.

O'Reilly scored an empty net goal on two shots in Saturday's 5-3 win over the Avalanche. He also won 21 of 28 faceoffs.

EDGE Analysis

After the Avalanche's tying goal was disallowed for a kicking motion, O'Reilly put away an empty-netter to seal the Blues' win. The 30-year-old center was in fine form last season with 24 goals and 30 helpers in 56 outings, and he should have a good chance of getting back over the 60-point mark with a full season on the schedule. O'Reilly's strong two-way play makes him a reliable No. 1, especially in fantasy formats that reward his work at the dot -- he enters the year with a career 55.7 winning percentage on faceoffs.

O'Reilly collected two assists and two shots in a 5-2 loss to Colorado in Game 4 on Sunday. He also went 13-for-23 (56.5 percent) in the faceoff circle.

EDGE Analysis

O'Reilly sprung Vladimir Tarasenko for a breakaway goal that broke a scoreless tie early in the second period. He later drew the secondary assist on Tarasenko's second goal of the game, this one on the power play, midway through the final frame. O'Reilly produced three assists in the series, albeit with a brutal minus-7 rating in four games.

O'Reilly notched a shorthanded assist and went 12-for-18 on faceoffs in Friday's 5-1 loss to the Avalanche in Game 3.

EDGE Analysis

O'Reilly set up Tyler Bozak for the Blues' lone goal in the second period. The 30-year-old O'Reilly has just the one assist to go with seven shots on net and a minus-6 rating through three playoff contests. He'll look to lead the Blues on an improbable series comeback, beginning with Sunday's Game 4.

O'Reilly managed an assist, three shots on goal and a plus-2 rating in Wednesday's 4-0 win over the Wild.

EDGE Analysis

O'Reilly continued his late-season surge with the helper -- he's now recorded seven goals and seven assists in his last 11 games. The star center is up to 53 points (24 tallies, 29 assists), 126 shots on net and a plus-25 rating through 55 contests.

O'Reilly managed an assist and two blocked shots in Monday's 2-1 overtime win over the Kings.

EDGE Analysis
