Hakeem Nicks is going to make the club of course. But his time in the tub is starting to aggravate the Giants. Nicks sat out practice entirely yesterday because of a nagging groin injury prompting coach Tom Coughlin to label his No. 1 receiver’s inability to stay healthy so far in training camp “frustrating.” “Certainly I want to see him on the field and he wants to be on the field” Coughlin said after the two-hour workout. “It’s frustrating but I’ve got to learn to control myself when it comes to that as well and just realize that — you know what? — he’s trying like heck to get out there.” Nicks who skipped the voluntary part of the Giants’ offseason program in part because of what he said was concern about potential injuries has been limited throughout the first week of camp by the groin strain. Yesterday Nicks spent time on the sideline stationary bike before observing the rest of the practice on the field with the coaches. His absence led to concern the problem is getting worse but Coughlin described it as a “little” injury and said the wideout’s availability remains day-to-day. “[The Giants’ trainers] just want to quiet it down and make sure that it heals before he goes back out and maybe makes it worse” Coughlin said. The Giants moved practice indoors because of the rain and quarterback Eli Manning struggled without the benefit of Nicks as a primary target. Manning threw two interceptions on passes intended for Victor Cruz in 11-on-11 drills. Coughlin wasn’t the only Giants coach to express a bit of impatience at Nicks’ constant injury battles. The former No. 1 pick was hampered all last year by ankle and foot woes.
