Saints player to watch

Fourth-year receiver Chris Olave — whose playing future was unsure after at least the fourth concussion of his NFL career caused him to miss the last eight games of last season — has made it through the first three games of this season without injury and leads the team in catches with 23.

Bills player to watch

Though offseason free-agent addition Joshua Palmer has made an impact with eight catches for 113 yards, the fifth-year receiver has yet to display his stretch-the-field ability. A big reason for that is opposing defenses protecting against the deep pass. That could change as early as this weekend should the Saints crowd the line in a bid to contain RB James Cook, who's 284 yards rushing rank second in the NFL entering Week 4.

Key matchup

Josh Allen versus Saints secondary. Allen has combined for five touchdowns passes in two home games, and is facing a defense that’s allowed seven TD passes so far this season. The Saints secondary is relatively stingy in allowing just 210 yards passing per outing. New Orleans, however, has allowed eight passes of 20 or more yards, including four against Seattle.

Key injuries

The Saints played last week without starting RT Taliese Fuaga because of knee and back ailments that could continue to affect his availability this week. DL Chase Young has yet to play this season after straining his calf during a Week 1 practice. ... Bills starting DT Ed Oliver (ankle) and LB Matt Milano (pectoral) remain question marks. Oliver has missed two games and Milano one. Starting right tackle Spencer Brown's status bears monitoring after missing practice Wednesday because of a calf injury.

Series notes

New Orleans has won four of five at Buffalo and not lost there since Oct. 30, 1983, the teams' first meeting at Orchard Park, New York. The Saints also have won five of the past six, including a 47-10 win in their most recent trip to Buffalo in 2017, which stands as the largest margin of victory in series history.

Fantasy tip

Kamara remains a must-start, but expectations should be measured. The Bills might be statistically porous against the run, but much of that is a result of allowing 238 yards rushing in a season-opening 41-40 win over Baltimore. The following week, Buffalo limited Breece Hall to 29 yards rushing in a 30-10 win at the New York Jets.
