Observations from Giants training camp on Thursday.

Seeing Malik Nabers running around the field for the first time since suffering a sprained ankle meant that the dynamic rookie wide receiver is a quick healer, a good sign for him and the Giants. 

The cards were out, meaning this was a slowed-down version of practice, with preparations for Saturday’s game at Houston in place.

Players on a scout team wore red jerseys simulating Stefon Diggs, Tank Dell and Nico Collins. 

During a team period late in practice, the voice of Alicia Keys blared “Empire State of Mind’’ louder than usual.

The starting offense was on the field, and this was preparation for crowd noise this weekend on the road against the Texans. 

In addition to Nabers returning, another rookie made it back as RB Tyrone Tracy (ankle) participated in individual drills.

G Jon Runyan (shoulder) remained out.
