The San Francisco 49ers returned to work on Tuesday after taking the day off on Monday. Each side of the football had its share of big plays in what was an entertaining practice. Here's what you need to now from Day 5 of 49ers training camp.

1. There were some notable lineup changes with guys coming back to practice and others landing on the injury report. Arik Armstead (hamstring) is week-to-week. Rookie Jullian Taylor stepped in with the first-team defense at the big end spot on base downs. Malcolm Smith (lower leg) was a full participant in practice after being taken off of PUP Tuesday morning. Smith took first-team reps at MIKE next to Reuben Foster. Jimmie Ward (tightness) and Brock Coyle (tightness) were both removed from practice prior to full-team work. Tyvis Powell took Ward's reps at corner.
